In one embodiment, the electronic device further includes a driving mechanism, which is connected to the housing assembly and used to drive the first housing and the second housing to move relative to each other in a predetermined direction.

As shown in FIG. 1 and FIG. 2 , the electronic device 100 according to the embodiment of the present application includes a shell assembly 10 and a flexible display screen 20 . The shell assembly 10 is a hollow structure. The electronic device 100 may also include a circuit board and a battery, and both the circuit board and the battery may be disposed inside the housing assembly 10 . The circuit board may integrate the processor, power management module, storage unit, baseband chip, etc. of the electronic device 100 . The flexible display screen 20 is communicatively connected to the circuit board, and the battery can power the flexible display screen 20 and the electronic components on the circuit board. Of course, the electronic device 100 may also include a camera module. The camera module is communicatively connected to the circuit board, and the battery can power the camera module. It can be understood that the electronic device 100 in the embodiment of the present application includes but is not limited to terminal devices such as mobile phones and tablet computers or other portable electronic devices. In the implementation of this application, a mobile phone is taken as an example for explanation.

As shown in FIG. 1 and FIG. 2 , in the embodiment of the present application, the shell assembly 10 has a folded state (as shown in FIG. (shown in Figure 1) and the unfolded state (shown in Figure 2) relative to the collapsed state. When the shell assembly 10 switches between the folded state and the unfolded state, the display area of the display interface 20a of the flexible display screen 20 can be adjusted. It can be understood that the flexible display screen 20 is disposed on the shell assembly 10. When the shell assembly 10 is in the unfolded state, the display area of the display interface 20a available for display on the flexible display screen 20 is larger to improve the use experience of the electronic device 100. At this time, The electronic device 100 has a larger overall size. When the case assembly 10 is in the folded state, the display area of the display interface 20a available for display on the flexible display screen 20 is smaller. At this time, the entire electronic device 100 has a relatively small overall size for easy portability.

In the embodiment of the present application, the shell assembly 10 includes a first shell 12 and a second shell 14. The first shell 12 and the second shell 14 are along a predetermined direction (the first direction X-X in FIGS. 1 and 2). ') Relative movement to switch the shell assembly 10 between the folded state and the unfolded state. Specifically, when the first housing 12 and the second housing 14 move relative to each other in a predetermined direction, the first housing 12 and the second housing 14 will drive the flexible display screen 20 to perform folding or flattening movements. With the relative movement of the first housing 12 and the second housing 14 , at least part of the structure of the flexible display screen 20 is extended from or retracted from the housing assembly 10 , thereby changing the display area of the electronic device 100 . To be precise, when the flexible display screen 20 is extended from the shell assembly 10, the display area of the display interface 20a increases; correspondingly, when the flexible display screen 20 is retracted into the shell assembly 10, the display area of the display interface 20a decreases.

As shown in FIGS. 1 to 3 , in the embodiment of the present application, the electronic device 100 includes a sliding assembly 30 , and the sliding assembly 30 is used to realize relative sliding of the first housing 12 and the second housing 14 .

Specifically, as shown in FIG. 4 , the sliding assembly 30 includes a guide rail 31 , a base 32 and a plurality of rigid balls 33 . The guide rail 31 has a guide groove 31a, the base 32 has a circulation channel 32a, and a plurality of rigid balls 33 are arranged along the guide groove 31a and the circulation channel 32a. When the base 32 moves along the guide rail 31, at least some of the plurality of rigid balls 33 enter or move out of the guide groove 31a through the circulation channel 32a. In this way, the rolling of the rigid balls 33 can be used to reduce the friction between the base 32 and the guide rail 31 . It can be understood that when the base 32 continues to move in one direction along the guide rail 31, the plurality of rigid balls 33 will roll circularly along the guide groove 31a and the circulation channel 32a.

The base 32 and the guide rail 31 elastically cooperate to absorb the deflection displacement when the base 32 moves along the guide rail 31, thereby maintaining smooth sliding between the base 32 and the guide rail 31, reducing movement resistance, and reducing the occurrence of jamming.

In some embodiments, the first housing 12 is connected to the guide rail 31 in the sliding assembly 30 , and the second housing 14 is connected to the base 32 of the sliding assembly 30 . The guide rail 31 is arranged along a predetermined direction, and the cooperation between the base 32 and the guide rail 31 is used to satisfy the relative movement of the first housing 12 and the second housing 14 . It can be understood that when the first housing 12 and the second housing 14 move relative to each other, the base 32 moves along the guide rail 31. At this time, the rigid balls 33 between the base 32 and the guide rail 31 achieve a sliding effect in a rolling manner. , thereby enabling the first housing 12 and the second housing 14 to move smoothly with each other.

There are many possibilities for the elastic fit between the base 32 and the guide rail 31 , which can be indirect elastic fit or direct elastic fit.

Exemplarily, as shown in FIG. 5 , the sliding assembly 30 includes a floating seat 34 and an elastic body 35 . The floating seat 34 is provided between the guide rail 31 and the base 32 . The elastic body 35 is provided between the floating seat 34 and the base 32 . . With this arrangement, the elastic body 35 can satisfy the elastic floating between the floating seat 34 and the base 32 . To be precise, the base 32 can move relative to the floating seat 34 under the action of the elastic body 35 , and the base 32 can move relative to the floating seat 34 During the movement, the elastic body 35 deforms. Therefore, when the base 32 is subjected to a deflection force in a direction perpendicular to the guide rail 31 , the base 32 can be deflected relative to the guide rail 31 . After the deflection force disappears, the elastic body 35 will recover its deformation so that the base 32 returns to its original position, thereby achieving the effect that the base 32 can elastically float relative to the guide rail 31 , that is, the elasticity between the base 32 and the guide rail 31 is achieved. Cooperate.

In some embodiments, as shown in FIG. 7 , the sliding component 30 includes elastic balls 36 . A plurality of elastic balls 36 are disposed in the guide groove 31 a and the circulation channel 32 a . When the base 32 moves along the guide rail 31 , the elastic balls 36 in the guide groove 31 a There is always at least one elastic ball 36 . In this embodiment, the elastic ball 36 has deformation characteristics, so that when the base 32 deflects relative to the guide rail 31 , the elastic ball 36 elastically contacts the guide rail 31 , thereby achieving elastic cooperation between the base 32 and the guide rail 31 .

Furthermore, the diameter of the elastic ball 36 is larger than the diameter of the rigid ball 33, so that the elastic ball 36 with a diameter larger than the rigid ball 33 can better exert the elastic effect, so that the base 32 can elastically float and maintain relative to the guide rail 31 within a certain deflection range. It cooperates stably with the guide rail 31 to ensure the stability of the movement of the base 32 along the guide rail 31 .

It can be understood that in the embodiment in which the sliding assembly 30 includes the floating seat 34 and the elastic body 35, elastic balls 36 can also be provided in the guide groove 31a and the circulation channel 32a, so that the elastic body 35 and the elastic balls 36 can be used to achieve multiple elastic buffering. As a result, the offset reset performance of the base 32 relative to the guide rail 31 is further improved.

It should be noted that in an embodiment in which the sliding assembly 30 includes a floating seat 34, the elastic balls 36 located in the guide groove 31a may be in elastic contact with the side of the floating seat 34 facing the guide rail 31, and then the guide rail 31 and the floating seat 34 to act as a flexible buffer.

In an embodiment in which the base 32 and the guide rail 31 are slidingly coupled through rigid balls 33, the elastic balls 36 located in the guide groove 31a may be in elastic contact with the side of the base 32 facing the guide rail 31, and then the guide rail 31 and the base 32 to act as a flexible buffer. In this embodiment, as shown in FIG. 7 , the base 32 includes a connecting body 321 and stoppers 322 detachably connected to both ends of the connecting body 321 . The circulation channel 32a is provided on the connecting body 321, and the stopper 322 has an arc-shaped groove 322a. The arc-shaped groove 322a is used to guide the rigid ball 33 to roll between the circulation channel 32a and the guide groove 31a. It can be understood that it is difficult to process the arc groove 322a and the circulation channel 32a directly on the complete base 32 at the same time. By dividing the base 32 into a detachable connector 321 and a stopper 322, it is easier to process the circulation channel 32a and the circulation channel 32a respectively. The arc-shaped groove 322a also facilitates the assembly of the rigid ball 33. In some embodiments, after the rigid balls 33 are loaded into the circulation channel 32a and the guide groove 31a, the stopper 322 is connected to the connecting body 321, so that the rigid balls 33 cannot easily fall off from between the base 32 and the guide rail 31. The stopper 322 and the connecting body 321 may be connected through screws, buckle connection or welding. The connection method between the two is not limited here.

The structure of the sliding assembly 30 will be further described below in conjunction with the arrangement of the "floating seat 34" and the "elastic ball 36".

As shown in FIG. 5 , the floating seat 34 has a receiving groove 34a and a groove 34b formed on the side wall of the receiving groove 34a. At least part of the guide rail 31 is located in the receiving groove 34a. The groove 34b and the guide groove 31a jointly define a ball channel. Both ends of the ball channel are respectively connected with both ends of the circulation channel 32a. In this embodiment, the ball channel and the circulation channel 32a form a closed loop, so that the rigid balls 33 can circulate and roll. Specifically, when the base 32 moves along the guide rail 31, a plurality of rigid balls 33 roll along the circulation channel 32a and the ball channel. With this arrangement, the plurality of rigid balls 33 realize relative movement between the floating seat 34 and the guide rail 31 in a rolling manner. Compared with the contact sliding between the floating seat 34 and the guide rail 31, this structure of this embodiment has smaller friction. Thus, the sliding assembly 30 can smoothly move the first housing 12 and the second housing 14 with each other.

Further, the base 32 has a mounting groove 32b. The width W1 of the notch 32c of the mounting groove 32b is smaller than the width W2 of the groove bottom 32d of the mounting groove 32b. The floating seat 34 includes a connected main body part 341 and a limiter. The position portion 342 and at least part of the main body portion 341 are located in the notch 32c. The limiting part 342 is opposite to the groove bottom 32d of the mounting groove 32b, and the width W3 of the limiting part 342 is greater than the width W1 of the notch 32c. In this way, the limiting part 342 will not be removed from the notch 32c, and the floating seat 34 and the base 32 has good stability.

Regarding the placement position of the elastic body 35 , it is sufficient as long as it can adapt to the elastic connection between the base 32 and the floating seat 34 . For example, in some embodiments, the elastic body 35 is provided on both the side of the limiting portion 342 facing the notch 32c and the side of the limiting portion 342 facing the groove bottom 32d. Specifically, the elastic body 35 is disposed between the side of the limiting portion 342 facing the notch 32c and the base 32, and between the side of the limiting portion 342 facing the groove bottom 32d and the base 32. In some embodiments, the elastic body 35 is disposed between the side wall of the slot 32c and the base 32.

The elastic body 35 can be a spring or a rubber pad. The type of the elastic body 35 is not limited here, as long as the elastic body 35 can be deformed by extrusion and recover its deformation after the extrusion force is removed.

As shown in FIG. 6 , in the embodiment in which the sliding assembly 30 includes a floating seat 34 , the sliding assembly 30 includes a conduit 37 . Both ends of the conduit 37 are connected to the floating seat 34 and the base 32 respectively. The conduit 37 is used to communicate with the circulation channel. 32a and the guide groove 31a, whereby the conduit 37 can guide the rigid ball 33 from the circulation channel 32a into the guide groove 31a, and guide the rigid ball 33 from the guide groove 31a into the circulation channel 32a. In this embodiment, the conduit 37 can meet the need for guiding the rigid balls 33 without hindering the elastic floating of the base 32 relative to the floating seat 34 . Specifically, the conduit 37 can be made of metal flexible materials such as carbon steel, cast steel, galvanized, stainless steel, etc., or can be made of non-metallic flexible materials such as polyvinyl chloride or silicone, which are not limited here.

It should be noted that there is a gap between the end of the conduit 37 close to the floating seat 34 and the guide rail 31. When the base 32 elastically floats relative to the floating seat 34, the gap between the conduit 37 and the guide rail 31 provides an appropriate position for the conduit 37. The avoidance space is used to reduce the probability of the conduit 37 coming into contact with the guide rail 31 when it moves with the base 32 and to reduce the friction when the conduit 37 contacts the guide rail 31, so that the movement of the base 32 relative to the guide rail 31 is less interfered by the conduit 37. This is beneficial to maintaining the smoothness of the movement of the base 32 along the guide rail 31 .

As shown in FIGS. 7 to 9 , in an embodiment in which the sliding assembly 30 includes elastic balls 36 , a plurality of elastic balls 36 and a plurality of rigid balls 33 are arranged alternately. Therefore, during the rolling process of the plurality of elastic balls 36 and the plurality of rigid balls 33, the adjacent rigid balls 33 can be cushioned by the elastic balls 36, thereby avoiding collisions between the rigid balls 33 and further improving the sliding assembly 30. Job stability.

It should be noted that since the elastic ball 36 has a certain deformation ability, when the guide rail 31 is relatively When the base 32 swings at a small angle, the guide rail 31 will deflect and press on the elastic balls 36, causing the elastic balls 36 to elastically deform.

For ease of understanding, the deflection of the guide rail 31 is described with the base 32 as a reference.

In the guide rail 31 assembly of the present application, the guide rail 31 can be deflected in the clockwise direction relative to the base 32, and can also be deflected in the counterclockwise direction. In this way, when the guide rail 31 is deflected to two extreme positions relative to the base 32, the deflection range can be determined.

As shown in FIG. 8 , when the guide rail 31 deflects clockwise to a certain angle and contacts the rigid ball 33 , the deflection angle of the guide rail 31 in the clockwise direction reaches the limit. As shown in FIG. 9 , when the guide rail 31 deflects counterclockwise to a certain angle and contacts the rigid ball 33 , the deflection angle of the guide rail 31 in the counterclockwise direction reaches the limit.

When the guide rail 31 rotates relative to the base 32 to the extreme position, it will be restricted by the rigid ball 33 and cannot continue to deflect. Correspondingly, the elastic deformation of the elastic ball 36 also reaches the upper limit of the corresponding extreme position. Therefore, when designing the sliding assembly 30 , it is only necessary to ensure that the deflection angle required for the function is within the upper limit of the designed deflection angle, and at the same time, the deformation amount of the elastic ball 36 under this limit deflection is within the upper limit of the elastic deformation amount of the elastic ball 36 alone.

It should be noted that due to the elastic fit between the base 32 and the guide rail 31, there is a margin for relative deflection between them. The base 32 can maintain the performance of sliding along the guide rail 31 within the deflection margin range, and will not cause jamming or jamming due to increased friction due to the offset of the base 32 relative to the guide rail 31 .

As shown in FIG. 10 , in some embodiments, the center lines of the guide groove 31 a and the circulation channel 32 a are located on the same plane, and the value range of the angle α that the base 32 and the guide rail 31 can deflect relative to the plane is: α ≤ 10° . With this arrangement, the deflection amplitude of the base 32 relative to the guide rail 31 is appropriate, not too large to affect the sliding effect of the sliding assembly 30 in the shell assembly 10, and not too small to have little effect in reducing movement resistance.

It should be noted that the power source for the relative movement of the first housing 12 and the second housing 14 may be manual or electric.

Specifically, when using the manual method, the user only needs to hold the first housing 12 and the second housing 14, and when moving in a direction away from each other, the second housing 14 can be placed in the deployed position. Correspondingly, when the first housing 12 is in the unfolded position, if the electronic device 100 needs to be folded, only the first housing 12 and the second housing 100 need to be folded. The housings 14 only need to move toward each other.

In an electric embodiment, the electronic device 100 includes a driving mechanism, which is connected to the housing assembly 10 and used to drive the first housing 12 and the second housing 14 to move relative to each other in a predetermined direction.

Specifically, the driving mechanism is used to drive the base 32 to move along the guide rail 31 . Based on the fact that the base 32 and the guide rail 31 are respectively connected to the first housing 12 and the second housing 14 to achieve sliding fit between the first housing 12 and the second housing 14, in this embodiment, the driving mechanism drives When the base 32 moves along the guide rail 31, the first housing 12 and the second housing 14 move relative to each other.

The driving mechanism includes driving parts, screw rods and nuts. The driving part is used to output torque, and the driving part may be a rotating motor or a micro motor. The screw rod is connected to the driving part and rotates under the driving of the driving part. The nut is threaded with the screw rod, so that when the screw rod rotates, the nut moves along the screw rod. It should be noted that the screw rod and the guide rail 31 are arranged in parallel, and the nut is connected to the base 32. The connection method between the nut and the base 32 includes but is not limited to welding, snap connection or hot melt connection. In this way, when the screw rod drives the nut to move, the nut will drive the base 32 to move along the guide rail 31 .

It should be noted that the driving mechanism is not limited to the above-mentioned structure. In some embodiments, the driving mechanism may be a belt transmission structure. For example, the driving mechanism includes a driving wheel, a transmission belt and a driven wheel. Both the driving wheel and the driven wheel cooperate with the transmission belt. When the driving wheel rotates, the driven wheel is driven to rotate through the transmission belt. In this embodiment, the transmission belt is connected to the base 32, and when the driving wheel rotates, the transmission belt drives the base 32 to move along the guide rail 31.

The technical features of the above embodiments can be combined in any way.
